Why did Metro add letters to the current naming convention for rail lines and bus rapid transit lines?
We updated line names to include a letter to help everyone, including riders with visual impairments, have a better journey. Customer feedback, research and testing revealed that letters are easier for everyone to understand than color alone.
What is changing?
The addition of letters to line colors will appear on station signage, maps, timetables, posters, digital platforms and everywhere else you find our colored dots and squares. The colors did not change, and we will continue to use them as we do now to indicate routes and service.
When is the change coming?
We’ve made the transition to the A Line (Blue) — there’s brand new signage on the A Line — and the E Line (Expo). The rest of our rail lines are now following suit.
Our goal is for all Metro Rail and Bus Rapid Transit stations to have updated line letter name signage within the next few years.
On digital platforms such as our website, digital kiosks and transit apps, you’ll start seeing changes within a few weeks. Printed material will be updated as the opportunity arises, and we will prioritize timetables, maps, posters and fact sheets in order to keep riders informed.
How were the letters chosen for the line names?
Letters are assigned in the order of each line’s original opening date. For instance, since the Blue Line was Metro’s first rail line to open in 1990, it becomes the A Line. All current and future lines will get the next letter in the alphabet based on its opening date.
What if I have questions?
We’re working hard to make the transition as smooth as possible, and we’re looking forward to our new, cohesive system in the near future. If you have questions or comments, please email us at email@example.com .
